_________________________

The game is "Gridrunner II", as released in Europe, but HES really liked the title of another Jeff Minter game and renamed it.

Attack of the Mutant Camels is sequel to Gridrunner. In this Centipede style game you play a retired captain of a starship, one of those who had won the previous war against aliens. You come out of retirement because the aliens are back, tougher than ever. Thus a second gridwar begins.

You pilot your ship and shoot at chains of pods coming at you. As you hit the pods, they break into smaller independent chains. The aliens seem to have a sense of humor, though. Each pod in the chain coming at you looks like a...camel. Flying camels from outer space.

As you start shooting the camels, you are attacked by guns from the bottom of the screen and from the left side of the screen. Even worse, a human traitor has joined the aliens, and when he appears on the screen, running across the grid on top, the guns get very accurate at shooting you. Luckily you can shoot traitors.

Other twists include deflectors, which turn your bullets and even ricochet them back at you. The enemy fires back too. And as you advance in level, the enemy changes the direction of their attack.
